Title: Noise protection circuit
IPC: G06T11/00
Filed: 1966-02-01
Abstract: 1,121,021. Television. RADIO CORPORATION OF AMERICA. 1 Feb., 1966. [26 Feb., 1965], No. 4495/66. Heading H4F. In a television synchronizing pulse separator circuit 17 comprising transistor 19 and selfbiasing circuit 20, a noise pulse extending beyond the preceding synchronizing pulse, normally biases the circuit 20, such that following synchronizing pulses cannot pass to the transistor. This fault is overcome in the invention, by disabling circuit 17 during periods when said excessive noise is detected. The emitter of transistor 19 is then passed to earth via a normally conducting transistor 22. When transistor 22 is cut off, transistor 19 is likewise cut off, such that the charging impedance of circuit 20 becomes very high, and the excessive noise pulse in the video signal 14a<SP>11</SP> has no effect on the bias set up by circuit 20. The video signal 14a<SP>1</SP> from the first stage of video amplifier 14 is passed to an A.G.C. circuit 16, comprising a normally cut-ofF transistor 28, a series transformer winding 31 whereby pulses, synchronous with the synchronizing pulses are induced to periodically render the transistor conductive, a potentiometer 36 for providing a bias (Vt), Fig. 2 (not shown), against which the voltage of the synchronizing pulses is compared, and a capacitor 29 across which the A.G.C. voltages is developed. The action of the A.G.C. circuit is such that the bottoms of the synchronizing pulses are kept at the voltage (Vt). The bias (Vt) produces a bias (V<SP>1</SP>t) at one side of diode 39. The other side of the diode receives the video signal 13<SP>1</SP> and the action of A.G.C. circuit 16 is such that the tops of the synchronizing pulses are at the voltage (V<SP>1</SP>t). A noise pulse extending below (V<SP>1</SP>t) thus causes diode 39 to conduct and results in transistor 22 being cut off.

Title: Continuous esterification process
Inventor: CASH WILFRID ERNEST
IPC: B01D3/18
Filed: 1952-02-23
Abstract: A mixture of a monohydric alcohol and an organic carboxylic acid, anhydride or acid ester or neutral ester of a relatively volatile alcohol is passed with an esterification catalyst concurrently through a series of at least three consecutive zones, each having independent heating means and maintained at such temperatures that fractionation of the reactants is substantially avoided, passing an entrainer countercurrently to the mixture, withdrawing entrained vapours from one or more zones in the region where the mixture is introduced, and withdrawing the esterified product from one or more zones in the region where the entrainer is introduced.  Non-volatile esters are those of lower volatility than any of the other components of the reaction mixture excluding the catalyst.  A relatively volatile alcohol is one which is more volatile than the first mentioned alcohol.  The countercurrent flow of entrainer need only be partial.  Many acids and anhydrides are specified representative, being phthalic acid and anhydride, sebacic, lactic, butyric, o-benzoyl-benzoic, maleic, citric, malonic and fumaric acids and acetic anhydride. Representative of alcohols specified are methyl, amyl and decyl alcohols, cyclohexanol, phenylethanol and 2-methoxy-ethanol.  Acid esters, e.g. mono-esters of the specified dicarboxylic acids may be esterified conveniently by first forming the mono-ester in the mixing zone in the presence of excess alcohol and then the solution of mono-ester in alcohol is lead through the reaction zones.  Mixed esters may be made.  Sulphuric acid is the preferred catalyst and is used in concentrations of 0.05-2, particularly 0.1-0.5, per cent by weight.  When making lower alkyl esters the entrainer is desirably the alcohol used for esterification; with alcohols of at least 5 carbon atoms per molecule, however, an aromatic hydrocarbon of 6-8 carbon atoms per molecule, e.g. benzene, is desirably present.  In alcoholysis an inert gas may be blown through the reaction mixture or an azeotrope former added. Diagrams of suitable apparatus are provided including an apparatus similar to a bubble cap fractionating column in which each reaction has separate heating means for independent temperature control.  In examples phthalic anhydride is reacted in the presence of sulphuric acid with (1) and (2) 2-ethyl hexanol with benzene as entrainer, and (3) n-butanol, and (4) methanol with the alcohols acting as entrainer the diesters being obtained in every case.

Abstract: 1,211,673. Time switches. SIEMENS A.G. 30 Jan., 1969 [31 Jan., 1968], No. 5102/69. Heading H1N. In a stepping programme controller for washing machines, for example, wherein, to reduce radio interference and damage to programming contacts due to arcing during rapid advance between stages, the controlled circuits are de-energized by means of a first switch which is opened automatically by the step-producing mechanism, a second switch arranged to be closed under control of the programmed actuator is connected in parallel with the first switch to prevent undesired opening of at least some circuits (for example, spin drier motor and pump motor) by the first switch during normal operational programme steps. In the particular embodiment shown a timer motor SM is energized from mains 1, 2 by closure of switch 8 when solenoid 4 is energized by depression of a button 3. The motor SM drives a timing member (not shown) and steps, via a clutch engaged when solenoid 4 is energized, a programmed actuating member (not shown) which controls various operations by means of contacts such as 22, 25, 19, 14, 15, and also maintains a "hold" contact 5. During rapid advance (by holding button 3 depressed, for example) the first switch 10 de-energizes the various operational circuits, and this also occurs during normal programme steps, occasioned by contacts 6 which are pulsed by the timing member. The second switch 11 is controlled by the programmed actuating member such that the first switch 10 is shorted only at certain places in the programme where it is desired to maintain devices such as a heater 23 and spin-drier motor 16, for example, in operation during stepping.
